Open mixingmill


Application :The mill is used for rubber plasticating, mixing, warming andsheeting.
Generaldesign:
1. The mill consists mainly for rolls, frame,bearing, roll nip adjusting, screw, heating and cooling device, emergency stop,lubrication system and such sections as electrical controls and, etc.
2.The main electric motor arrives the front and rear rolls to rotate oppositelythrough reduar, driving geras and friction gears.
Mainfeatures:
1. The rolleradopts the vanadium titanium metal alloy chilled cast iron and its surface ishard and wear-proof with long service life. The internal cavity is processed tomake temperature well proportioned to the roller surface.
2. The speed reducer is the hard-tooth surfacegear reducer of class 4 precision, which is durable and with lownoise.
3. The machine is also equipped with anemergency brake device. When an emergency arises, just push the emergency stopbutton, the machine will stop immediately. It is safe and reliable.
4. The machine is equipped with an overloadprotection device to prevent the main components from being damaged.
5. The transmission system adopts a hardenedtooth-surface reducer, which has a compact structure with higher transmissionefficiency, lower noise and longer service life.
6. The base frame is a whole framework, whichis convenient for installation.
7. The seal structure with special design caneliminate the leaking phenomenon of lubricating oil.
